Puly Caff Liquid Descaler for Espresso or Coffee Machines




Descaling is necessary if the espresso machine is using hard water and had accumulated a lot of minerals.
Severe amount of mineral build-ups can cause sensors unable to work effectively creating various forms of issues. It can be hazardous.
We do not recommend using hard or Alkaline water for coffee machines as the first line of defence.

This product is for any coffee machines, particularly for espresso machines with boilers.
Descaling can be a challenging process and not for amateurs. For the best effect with the least damage, it should be done by a qualified technician.

Puly Caff Liquid Descaler for Espresso or Coffee Machines is in liquid form, is food grade and in individual bottles for easier storage.
The liquid version can be used in room temperature water and studied to have the maximum performances and safe on yellow metals boilers (copper, brass) and INOX.
It can also be used for small domestic coffee machines, water heaters, kettles, etc.



If the water source is soft and the machine wasn’t for commercial heavy duty usage, descaling is not necessary until 2-3 years later, else it’s recommended to be done yearly.

Using a water softener or using distilled water as a preventive measure is more recommended than worrying about descaling.
Users can use this product for regular preventive descaling to clear light layers of build up before it accumulates.

If the water source is hard, it’s necessary to connect to a water softener before water intake else it will require descaling much sooner.



The instructions below are for clearing light layers of build-ups and can be taken as a preventive descaling from massive build ups.

If your machine wasn’t purchased from Fine Coffee Company, please refer to your vendor for instructions.



For light and preventive descaling, it’s possible that the user can do it themselves.
For severe cases, please contact a qualified serviceman.

We will suggest requesting for professional help due to the complications.



1. NEVER allow your pump to activate for more than 60 seconds. Stop and allow an equal period of rest time after each activation.

2. DO NOT perform descaling and grouphead flushing with detergent back to back or together, keep them done separately at intervals of few days of use later.
